Description

Technical Field

[0001] The present disclosure relates to a display device and an operating method thereof, and more particularly, to a display device that communicates with an external speaker using Bluetooth (registered trademark; the same shall apply hereinafter) and a system including the same.

Background Art

[0002] Digital television services using wired or wireless communication networks have become widespread. Digital television services can provide various services that could not be provided by conventional analog broadcast services.

[0003] For example, in the case of IPTV (Internet Protocol Television), which is a type of digital television service, and smart television services, bidirectionality is provided in which a user can actively select the type of program to be viewed, viewing time, etc. IPTV and smart television services can also provide various additional services based on such bidirectionality, such as Internet search, home shopping, online games, and the like.

[0004] Such a display device can also transmit and receive data with various electronic devices in a wired or wireless manner. For example, the display device can communicate and connect with an external speaker using the Bluetooth method, which is one of the short-distance communication methods. When the display device transmits an audio signal to the external speaker, the same audio can also be output through the display device and the external speaker, or different audio can be output to provide surround sound to the user.

[0005] On the other hand, because the display device and external speakers have different configurations, specifications, and settings related to audio output, there is a problem in that it is difficult to provide the user with a unified audio output from the display device and external speakers. Furthermore, if the sound field effects set for the display device and external speakers are different, audio with different sound field effects will be output from the display device and external speakers, making it impossible to provide a unified audio. In addition, even if an audio signal with a predetermined sound field effect applied is transmitted to the external speaker by the display device, if the external speaker applies the predetermined sound field effect to the audio signal again, it is possible that audio with a sound field effect different from the predetermined sound field effect will be output from the external speaker, making it impossible to provide a unified audio.

[0029] The tuner 131 can select a specific broadcast channel by channel selection command. The tuner 131 can receive broadcast signals for the selected specific broadcast channel.

[0030] The demodulator 132 can separate the received broadcast signal into a video signal, an audio signal, and data signals associated with the broadcast program, and can restore the separated video signal, audio signal, and data signals into an output-ready form.

[0031] The external device interface 135 can receive applications or application lists from adjacent external devices and transmit them to the controller 170 or memory 140.

[0032] The external device interface 135 can provide a connection path between the display device 100 and an external device. The external device interface 135 can receive one or more video and audio outputs from an external device connected to the display device 100 wirelessly or via a wired connection and transmit them to the controller 170. The external device interface 135 may include multiple external input terminals.

[0033] Video signals from external devices input via the external device interface 135 can be output via the display 180. Audio signals from external devices input via the external device interface 135 can be output via the speaker 185.

[0034] External devices that can be connected to the external device interface 135 may be any one of the following: a set-top box, a Blu-ray (registered trademark; hereinafter the same), a DVD player, a game console, a soundbar, a smartphone, a PC, a USB memory stick, or a home theater system; this is merely an example.

[0035] The network interface 133 can provide an interface for connecting the display device 100 to a wired / wireless network, including the Internet. The network interface 133 can transmit or receive data with other users or other electronic devices via the connected network or other networks linked to the connected network.

[0036] Furthermore, the display device 100 can transmit some of the content data stored in the display device 100 to other users or other electronic devices that have been pre-registered in the display device 100, or to selected users or selected electronic devices.

[0037] The network interface 133 can connect to a predetermined web page via the connected network or another network linked to the connected network. That is, it can connect to a predetermined web page via the network and send or receive data with the corresponding server.

[0038] Furthermore, the network interface 133 can receive content or data provided by content providers or network operators. In other words, the network interface 133 can receive content such as movies, advertisements, games, VOD, and broadcast signals, as well as related information, provided by content providers or network providers via the network.

[0039] Furthermore, the network interface 133 can receive firmware update information and update files provided by the network operator, and can transmit data to the internet, content providers, or network operators.

[0040] The network interface 133 can select and receive desired applications from among those publicly available (open) applications via the network.

[0041] The memory 140 can store programs for each signal processing and control within the controller 170, and can also store processed video, audio, or data signals.

[0042] Furthermore, the memory 140 can also function to temporarily store video, audio, or data signals input from the external device interface 135 or the network interface 133, and can also store information related to a predetermined image through its channel memory function.

[0043] Memory 140 can store applications or application lists input from the external device interface 135 or the network interface 133.

[0044] The display device 100 can play and provide to the user content files (video files, still image files, music files, document files, application files, etc.) stored in the memory 140.

[0045] The user input interface 150 can transmit signals input by the user to the controller 170, or transmit signals from the controller 170 to the user. For example, the user input interface 150 can receive and process control signals such as power on / off, channel selection, and screen settings from the remote control device 200 using various communication methods such as Bluetooth, Ultra Wideband (WB), ZigBee, Radio Frequency (RF) communication, or infrared (IR) communication, or it can process control signals from the controller 170 to transmit them to the remote control device 200.

[0046] Furthermore, the user input interface 150 can transmit control signals input from local keys (not shown), such as the power key, channel key, volume key, and setting value, to the controller 170.

[0047] The video signal processed by the controller 170 can be input to the display 180 and displayed as the corresponding video signal. Furthermore, the video signal processed by the controller 170 can be input to an external output device via the external device interface 135.

[0048] The audio signal processed by the controller 170 can be output as audio from the speaker 185. Furthermore, the audio signal processed by the controller 170 can be input to an external output device via the external device interface 135.

[0049] In addition, the controller 170 can control the overall operation of the display device 100.

[0050] Furthermore, the controller 170 can control the display device 100 by user commands or internal programs input via the user input interface 150, and can connect to a network to allow users to download desired applications or application lists into the display device 100.

[0051] The controller 170 ensures that the channel information selected by the user, along with the processed video or audio signal, is output via the display 180 or speaker 185.

[0052] Furthermore, the controller 170, upon receiving an external device video playback command via the user input interface 150, enables the output of video signals or audio signals from an external device, such as a camera or video camera, input via the external device interface 135, through the display 180 or speaker 185.

[0053] On the other hand, the controller 170 can control the display 180 to display video, for example, broadcast video input via the tuner 131, external input video input via the external device interface 135, video input via the network interface unit, or video stored in the memory 140 to be displayed on the display 180. In this case, the video displayed on the display 180 may be a still image or a moving image, and may be 2D video or 3D video.

[0054] Furthermore, the controller 170 can control the playback of content stored in the display device 100, received broadcast content, or external input content input from an external source. This content may take various forms, such as broadcast video, external input video, audio files, still images, connected web pages, and document files.

[0055] The wireless communication interface 173 can communicate with external devices via wired or wireless connection. The wireless communication interface 173 is capable of short-range communication with external devices. For this purpose, the wireless communication interface 173 uses Bluetooth. TM The wireless communication interface 173 can support short-range communication using at least one of the following technologies: RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC (Near Field Communication), Wi-Fi (Wireless-Fidelity), Wi-Fi Direct, and Wireless USB (Wireless Universal Serial Bus). Such a wireless communication interface 173 can support wireless communication between the display device 100 and a wireless communication system, between the display device 100 and other display devices 100, or between the display device 100 and a network where the display device (100, or an external server) is located, via a Wireless Area Network. The Near Field Network may also be a Wireless Personal Area Network.

[0056] Here, the other display device 100 may be a wearable device (e.g., a smart watch, smart glasses, HMD (head-mounted display)), a mobile terminal such as a smartphone, that is capable of exchanging (or interacting with) the display device 100 according to this disclosure. The wireless communication interface 173 can sense (or recognize) a communicable wearable device in the vicinity of the display device 100.

[0057] Furthermore, if the sensed wearable device is a device authenticated to communicate with the display device 100 according to this disclosure, the controller 170 can transmit at least a portion of the data processed in the display device 100 to the wearable device via the wireless communication interface 173. Thus, the user of the wearable device can utilize the data processed in the display device 100 through the wearable device.

[0058] The display 180 can generate drive signals by converting video signals, data signals, OSD signals processed by the controller 170, or video signals, data signals, etc., received at the external device interface 135 into R, G, and B signals, respectively.

[0059] On the other hand, the display device 100 shown in Figure 1 is merely one embodiment of the present disclosure, so some of the illustrated components may be integrated, added, or omitted depending on the specifications of the display device 100 that is actually implemented.

[0060] In other words, two or more components may be combined into one component as needed, or one component may be subdivided into two or more components. Furthermore, the functions performed in each block are for illustrative purposes only in illustrating embodiments of this disclosure, and their specific operations or devices do not limit the scope of the rights of this disclosure.

[0061] According to other embodiments of the present disclosure, the display device 100 can also receive and play video via a network interface 133 or an external device interface 135 without comprising a tuner 131 and a demodulator 132, unlike the display device 100 shown in Figure 1.

[0062] For example, the display device 100 may be implemented by separating it into a video processing device, such as a set-top box, for receiving broadcast signals or content from various network services, and a content playback device for playing the content input from the video processing device.

[0063] In this case, the operation method of the display device according to the embodiments of the present disclosure described below can be performed not only by the display device 100 as described with reference to Figure 1, but also by any one of the following: an image processing device such as the separated set-top box or a content playback device equipped with a display 180 and a speaker 185.

[0064] Next, with reference to Figures 2 and 3, a remote control device according to one embodiment of the present disclosure will be described.

[0065] Figure 2 is a block diagram of a remote control device according to one embodiment of the present disclosure, and Figure 3 is a diagram showing an example of the configuration of a remote control device according to one embodiment of the present disclosure.

[0066] First, as shown in Figure 2, the remote control device 200 may include a fingerprint recognition device 210, a wireless communication circuit 220, a user input interface 230, a sensor 240, an output interface 250, a power supply circuit 260, a memory 270, a controller 280, and a microphone 290.

[0067] As shown in Figure 2, the wireless communication circuit 220 transmits and receives signals to any one of the display devices according to the embodiments of this disclosure described above.

[0068] The remote control device 200 may include an RF circuit 221 capable of sending and receiving signals with the display device 100 according to the RF communication standard, and an IR circuit 223 capable of sending and receiving signals with the display device 100 according to the IR communication standard. The remote control device 200 may also include a Bluetooth circuit 225 capable of sending and receiving signals with the display device 100 according to the Bluetooth communication standard. Furthermore, the remote control device 200 may include an NFC (Near Field Communication) circuit 227 capable of sending and receiving signals with the display device 100 according to the NFC communication standard, and a WLAN (Wireless LAN) circuit 229 capable of sending and receiving signals with the display device 100 according to the WLAN (Wireless LAN) communication standard.

[0069] Furthermore, the remote control device 200 transmits a signal containing information about the movement of the remote control device 200 to the display device 100 via the wireless communication circuit 220.

[0070] On the other hand, the remote control device 200 can receive signals transmitted by the display device 100 via the RF circuit 221 and, if necessary, can send commands to the display device 100 via the IR circuit 223 regarding power on / off, channel change, volume change, etc.

[0071] The user input interface 230 may consist of a keypad, buttons, a touchpad, or a touchscreen. The user can input commands related to the display device 100 to the remote control device 200 by operating the user input interface 230. If the user input interface 230 includes hard key buttons, the user can input commands related to the display device 100 to the remote control device 200 by pushing the hard key buttons. This will be explained with reference to Figure 3.

[0072] As shown in Figure 3, the remote control device 200 may include multiple buttons. These multiple buttons may include a fingerprint recognition button 212, a power button 231, a home button 232, a live button 233, an external input button 234, a volume control button 235, a voice recognition button 236, a channel change button 237, a confirmation button 238, and a back button 239.

[0073] The fingerprint recognition button 212 may be a button for recognizing the user's fingerprint. In one embodiment, the fingerprint recognition button 212 may be pushable and capable of receiving both push and fingerprint recognition actions.

[0074] The power button 231 may be a button for turning the power of the display device 100 on or off.

[0075] The home button 232 may be a button for moving to the home screen of the display device 100.

[0076] The live button 233 may be a button for displaying a live broadcast program.

[0077] The external input button 234 may be a button for receiving an external input connected to the display device 100.

[0078] The volume control button 235 may be a button for adjusting the volume level output by the display device 100.

[0079] The voice recognition button 236 may be a button for receiving and recognizing the user's voice.

[0080] The channel change button 237 may be a button for receiving the broadcast signal of a specific broadcast channel.

[0081] The confirmation button 238 is a button for selecting a specific function, and the back button 239 may be a button for returning to the previous screen.

[0082] Let's explain Figure 2 again.

[0083] If the user input interface 230 includes a touchscreen, the user can input commands related to the display device 100 to the remote control device 200 by touching the soft keys on the touchscreen. Furthermore, the user input interface 230 may include various types of input means that the user can operate, such as scroll keys and jog keys, and this embodiment does not limit the scope of the rights of this disclosure.

[0084] The sensor 240 may include a gyro sensor 241 or an accelerometer 243, and the gyro sensor 241 can sense information regarding the movement of the remote control device 200.

[0085] For example, the gyro sensor 241 can sense information regarding the operation of the remote control device 200 based on the x, y, and z axes, and the acceleration sensor 243 can sense information regarding the movement speed of the remote control device 200. On the other hand, the remote control device 200 may also be equipped with a distance measuring sensor, which can sense the distance to the display 180 of the display device 100.

[0086] The output interface 250 can output video or audio signals that correspond to the operation of the user input interface 230 or to signals transmitted from the display device 100.

[0087] The user can recognize whether the user input interface 230 is being operated or whether the display device 100 is being controlled by the output interface 250.

[0088] For example, the output interface 250 may include an LED 251 that lights up when the user input interface 230 is operated or when signals are sent and received with the display device 100 via the wireless communication circuit 220, a vibrator 253 that generates vibrations, a speaker 255 that outputs sound, or a display 257 that outputs images.

[0089] Furthermore, the power supply circuit 260 supplies power to the remote control device 200, and if the remote control device 200 does not operate for a predetermined period of time, the power supply is interrupted, thereby reducing power waste.

[0090] The power supply circuit 260 can resume power supply when a predetermined key provided on the remote control device 200 is operated.

[0091] The memory 270 can store various programs, application data, and other information necessary for controlling or operating the remote control device 200.

[0092] When the remote control device 200 transmits and receives signals wirelessly with the display device 100 via the RF circuit 221, the remote control device 200 and the display device 100 transmit and receive signals via a predetermined frequency band.

[0093] The controller 280 of the remote control device 200 can store and refer to information in its memory 270, such as the frequency band that can wirelessly transmit and receive signals with the display device 100 paired with the remote control device 200.

[0094] The controller 280 controls various matters related to the control of the remote control device 200. The controller 280 can transmit signals corresponding to predetermined key operations of the user input interface 230 or signals corresponding to the movement of the remote control device 200 sensed by the sensor 240 to the display device 100 via the wireless communication circuit 220.

[0095] Furthermore, the microphone 290 of the remote control device 200 can acquire sound.

[0096] Multiple microphones 290 may be provided.

[0097] Next, we will explain Figure 4.

[0098] Figure 4 shows an example of utilizing a remote control device according to an embodiment of the present disclosure.

[0099] Figure 4(a) illustrates that a pointer 205 corresponding to the remote control device 200 is displayed on the display 180.

[0100] The user can move or rotate the remote control device 200 up and down, left and right. The pointer 205 displayed on the display 180 of the display device 100 corresponds to the movement of the remote control device 200. Since the pointer 205 moves and is displayed according to the movement in 3D space as shown in the diagram, such a remote control device 200 may be named a spatial remote control.

[0101] Figure 4(b) illustrates that when the user moves the remote control device 200 to the left, the pointer 205 displayed on the display 180 of the display device 100 also moves to the left in response.

[0102] Information regarding the movement of the remote control device 200, as detected by the sensor of the remote control device 200, is transmitted to the display device 100. The display device 100 can calculate the coordinates of the pointer 205 from the information regarding the movement of the remote control device 200. The display device 100 can then display the pointer 205 in accordance with the calculated coordinates.

[0103] Figure 4(c) illustrates a case where a specific button on the remote control device 200 is pressed, and the user moves the remote control device 200 away from the display 180. This allows the selected area on the display 180 corresponding to the pointer 205 to be zoomed in and enlarged.

[0104] Conversely, if the user moves the remote control device 200 closer to the display 180, the selected area on the display 180 corresponding to the pointer 205 can be zoomed out and displayed in a reduced size.

[0105] On the other hand, when the remote control device 200 moves away from the display 180, the selection area is zoomed out, and when the remote control device 200 moves closer to the display 180, the selection area is zoomed in.

[0106] Furthermore, when a specific button in the remote control device 200 is pressed, the recognition of up / down and left / right movement can be excluded. That is, when the remote control device 200 moves away from or closer to the display 180, up / down, left / right movement is not recognized, and only forward / backward movement is recognized. When no specific button in the remote control device 200 is pressed, only the pointer 205 moves in accordance with the up / down, left / right movement of the remote control device 200.

[0107] On the other hand, the movement speed and direction of the pointer 205 can correspond to the movement speed and direction of the remote control device 200.

[0108] On the other hand, in this specification, a pointer refers to an object displayed on the display 180 in response to the operation of the remote control device 200. Therefore, in addition to the arrow shape shown in the drawing as the pointer 205, objects of various shapes are possible. For example, it could be a concept that includes a point, cursor, prompt, or thick outline. Furthermore, the pointer 205 can be displayed corresponding to a single point on either the horizontal or vertical axis of the display 180, or it can be displayed corresponding to multiple points such as a line or surface.

[0109] Figure 5 shows an example of a system configuration according to one embodiment of the present disclosure.

[0110] As shown in Figure 5, the system 10 may include a display device 100 and one or more external speakers 500-1, 500-2.

[0111] The display device 100 can establish a Bluetooth connection with an external speaker. The display device 100 can perform the pairing and connection process with the external speaker. Thereafter, the display device 100 can transmit an audio signal to the external speaker, and the external speaker can output audio based on the audio signal.

[0112] The display device 100 and one or more external speakers 500-1, 500-2 can output audio to produce surround sound effects. For example, the display device 100 can output the main audio from the overall audio, and one or more external speakers 500-1, 500-2 can output the sub-audio from the overall audio.

[0113] External speakers 500-1 and 500-2 can output audio corresponding to the audio signal received from the display device 100 without modification.

[0114] External speakers 500-1 and 500-2 can process audio signals received from the display device 100 and output audio corresponding to the processed audio signals. For example, external speakers 500-1 and 500-2 can process audio signals so that sound field effects are applied by equalizer settings. For example, external speakers 500-1 and 500-2 can process audio signals using a predetermined audio codec (e.g., Dolby Atmos).

[0115] External speakers 500-1 and 500-2 may be, but are not limited to, a soundbar or portable speaker in the shape of a bar that extends long along a predetermined direction.

[0116] Figures 6 to 9c are diagrams referenced in the description of the connection between a display device and an external speaker according to embodiments of the present disclosure.

[0117] As shown in Figure 6, the user can use the pointer 205 displayed on the display 180 to select items 620 from the list 610 for audio output devices that correspond to the external speaker 500 and the speaker of the display device 100, in order to listen to audio via the display device 100 and the external speaker 500. This disclosure will be explained based on the premise that audio is output via the display device 100 and the external speaker 500.

[0118] As shown in Figure 7, the display device 100 can output a list of external speakers to be connected to. The list of external speakers may include external speakers already registered with the display device 100, and external speakers that are currently available for connection. The display device 100 can output objects 710 and 720 corresponding to each external speaker included in the list of external speakers.

[0119] The user can use the pointer 205 to select at least one of the objects 710, 720, which correspond to each external speaker. The display device 100 can perform the pairing and connection process for the external speaker corresponding to the object selected by the user.

[0120] As shown in Figure 8a, the display device 100 can output a screen (hereinafter referred to as the playback option setting screen) for setting the audio output method via the display 180.

[0121] The playback options settings screen may include an object 810 that supports surround sound provision and an object 820 that supports identical audio provision. The object 810 that supports surround sound provision can support a mode in which either the display device 100 or the external speaker 500 outputs the main audio and the other outputs the sub-audio, thereby producing a three-dimensional sound. The object 820 that supports identical audio provision can support a mode in which the display device 100 and the external speaker 500 output the same audio.

[0122] After the user uses the pointer 205 to select one of the objects 810 or 820 included in the playback option settings screen, they can then select the confirmation object 800. Based on the user input of selecting one of the objects 810 or 820 included in the playback option settings screen, the display device 100 can determine the audio output mode (hereinafter referred to as the audio mode).

[0123] As shown in Figure 8b, when the predetermined mode is determined to be the audio mode, the display device 100 can output an object 830 indicating the setting of the predetermined mode via the display 180. The predetermined mode may be a mode in which audio is output to produce surround sound effects using an external speaker 500 that communicates with the display device 100 via a previously set protocol and the speaker of the display device 100.

[0124] As shown in Figure 8c, the display device 100 can output an indicator 840 indicating the setting of a predetermined mode when the audio mode is set to a predetermined mode. The indicator 840 indicating the setting of a predetermined mode can be displayed in the item of the list 610 for the audio output device.

[0125] As shown in Figure 9a, when the audio mode is set to a mode that outputs audio to produce surround sound effects, the display device 100 can display a screen (hereinafter referred to as the audio type setting screen) for setting the type of audio output from the externally connected speaker 500.

[0126] The audio type setting screen may include a list 900 for external speakers registered with the display device 100. The list 900 for external speakers registered with the display device 100 may include external speakers 500 that are currently connected via communication. The list 900 for external speakers registered with the display device 100 may also include external speakers that are currently disconnected from communication.

[0127] The audio type settings screen may include an object 910 for setting the type of audio output from the external speaker 500. The user can change the type of audio output from the external speaker 500 using the pointer 205.

[0128] The audio type settings screen may include an object 911 corresponding to the currently connected external speaker 500. The user can use the pointer 205 to change the position of the object 911 corresponding to the external speaker 500 on the screen.

[0129] Here, the display device 100 can determine the position of the external speaker 500 relative to the display device 100, corresponding to the position of the object 911 corresponding to the external speaker 500 on the screen. In some embodiments, the display device 100 can also identify an object included in an image captured by the provided camera and determine the position of the external speaker 500 relative to the display device 100.

[0130] The audio mode of the display device 100 can be changed in response to a change in the type of audio output from the externally connected speaker 500. For example, if the external speaker 500 is configured to output main audio, the audio mode can be set to a mode where the external speaker 500 outputs main audio and the display device 100 outputs sub-audio. For example, if the external speaker 500 is configured to output sub-audio, the display device 100 can be set to a mode where the main audio outputs and the external speaker 500 outputs sub-audio.

[0131] According to one embodiment, the display device 100 can recommend the type of audio output from the connected external speaker 500 based on the specifications, location, etc. of the connected external speaker 500. For example, if the connected external speaker 500 is a device of a type that has already been set (e.g., a soundbar), the display device 100 can recommend the type of audio output from the connected external speaker 500 as the main audio. For example, if the connected external speaker 500 is currently located in front of the display device 100, the display device 100 can recommend the type of audio output from the connected external speaker 500 as the main audio.

[0132] As shown in Figures 9b and 9c, multiple external speakers 500 can be connected to the display device 100 via communication.

[0133] The audio type setting screen may include objects 921 and 931 corresponding to multiple external speakers 500 that are currently connected. The first object 921 can correspond to the first external speaker, and the second object 931 can correspond to the second external speaker. The user can change the position of objects 921 and 931 corresponding to the multiple external speakers 500 using the pointer 205. Here, the display device 100 can determine the positions in which the multiple external speakers 500 are arranged relative to the display device 100, based on the positions of objects 921 and 931 corresponding to the multiple external speakers 500.

[0134] The audio type setting screen may include an object 920 for setting the type of audio output from the first external speaker and / or an object 930 for setting the type of audio output from the second external speaker.

[0135] The user can use pointer 205 to change the type of audio output from the external speaker.

[0136] For example, when pointer 205 is located in the list 900 for external speakers, corresponding to the first external speaker, object 920, which sets the type of audio output from the first external speaker, can be activated and displayed. Here, the first object 921 can be displayed in a predetermined color. On the other hand, the display device 100 can also transmit an audio signal that has already been set to the first external speaker. The first external speaker can output audio corresponding to the audio signal received from the display device 100.

[0137] For example, if pointer 205 is located in the list 900 for external speakers and corresponds to the second external speaker, object 930, which sets the type of audio output from the second external speaker, can be activated and displayed. Here, the first object 931 can be displayed in a predetermined color. On the other hand, the display device 100 can also transmit an audio signal that has already been set to the second external speaker. The second external speaker can output audio corresponding to the audio signal received from the display device 100.

[0138] The display device 100 can recommend the type of audio output from the connected external speakers 500 based on the specifications and location of the connected external speakers 500. For example, if both the first and second external speakers are not devices of a type that has already been set (e.g., a soundbar), the display device 100 can recommend the type of audio output from the connected first and second external speakers as sub-audio. For example, if multiple connected external speakers 500 are located to the left and right of the display device 100, the display device 100 can recommend the type of audio output from the connected external speakers 500 as sub-audio.

[0139] Figure 10 is a flowchart referenced in the description of the operation of the system according to one embodiment of the present disclosure. The following description is based on the assumption that the display device 100 and the external speaker 500 support the Bluetooth communication standard.

[0140] As shown in Figure 10, the display device 100 and the external speaker 500 can connect to each other via a Bluetooth communication profile in S1001 operation. The Bluetooth communication profile may include A2DP (Advanced Audio Distribution Profile) and AVRCP (Audio / Video Remote Control Profile). A2DP may be a profile for transmitting audio data in one direction. AVRCP may be a profile for wirelessly controlling Bluetooth devices. For example, AVRCP may be a profile that includes information related to controlling the volume of a Bluetooth device, playing and stopping audio, etc.

[0141] The display device 100 can transmit its device information to the external speaker 500 in operation S1002. The display device 100 can transmit its device information using Bluetooth vendor-specific commands (VSC). This disclosure illustrates how devices included in the system 10 can communicate information, commands, etc., with each other using vendor-specific commands (VSC).

[0142] The device information of the display device 100 may include manufacturer information, device type information, information indicating that it is a source device that provides audio signals, and information regarding the functions that the display device 100 provides.

[0143] The functions provided by the display device 100 may include volume synchronization support and support for a predetermined audio codec (e.g., Dolby Atmos). Volume synchronization support may mean a function that adjusts the volume of the external speaker 500 in accordance with the volume level of the display device 100.

[0144] The external speaker 500 can transmit device information to the display device 100 in operation S1003.

[0145] The device information for the external speaker 500 may include manufacturer information, device type information, information indicating that it is a sink device that receives audio signals, information about the functions provided by the external speaker 500, and information about the audio output delay.

[0146] The functions provided by the external speaker 500 may include volume synchronization support, support for a specified audio codec (e.g., Dolby Atmos), surround sound effect support, and power synchronization support. Power synchronization support may mean a function that adjusts the on / off state of one of the power supplies, either the display device 100 or the external speaker 500, by turning it on / off.

[0147] Information regarding the audio output delay may include a delay value for the audio output delay, which is the difference between the time when audio is output from the display device 100 and the time when audio is output from the external speaker 500. For example, information regarding the audio output delay may include the delay value when one external speaker 500 is connected and the delay value when two identical external speakers 500 are connected.

[0148] According to one embodiment, the display device 100 can obtain information about the external speaker 500 based on the Extended Inquiry Response (EIR) transmitted by the external speaker 500 before establishing a connection via a Bluetooth communication profile. For example, the EIR may include protocol version information, device type information, information about the functions provided by the external speaker 500, and information about the audio output delay.

[0149] On the other hand, depending on the embodiment, the external speaker 500 can transmit its own device information to the display device 100 without transmitting any device information from the display device 100.

[0150] The display device 100 can determine the audio mode in operation S1004. The display device 100 can determine the audio mode based on the settings for surround sound effects and / or the device information of the external speaker 500.

[0151] For example, if surround sound effects are not provided, the audio mode can be set to the first audio mode. When the audio mode is set to the first audio mode, the same audio can be output from the speakers of the display device 100 and the external speakers 500.

[0152] For example, if surround sound effects are enabled and the external speaker 500 is not a device of a type already configured (e.g., a soundbar), the audio mode can be set to the second audio mode. When the audio mode is set to the second audio mode, the main audio can be output through the speakers of the display device 100, and the sub-audio can be output through the external speaker 500.

[0153] For example, if the system is configured to provide surround sound effects and the external speaker 500 is a device that is already configured (e.g., a soundbar), the audio mode can be set to the third audio mode. When the audio mode is set to the third audio mode, sub-audio can be output through the speakers of the display device 100, and main audio can be output through the external speaker 500.

[0154] The display device 100 can, in operation S1005, transmit audio output corresponding to the audio mode and related commands to the external speaker 500. The audio output and related commands may include commands for volume setting by volume synchronization, commands for using a predetermined audio codec (e.g., Dolby Atmos), commands for applying sound field effects by equalizer settings, and commands for requesting the transmission of predetermined information.

[0155] In operation S1006, the external speaker 500 can determine the audio output and associated settings based on the audio output received from the display device 100 and associated commands. For example, the external speaker 500 can activate / deactivate the use of a predetermined audio codec (e.g., Dolby Atmos) according to a command regarding the use of a predetermined audio codec (e.g., Dolby Atmos). For example, the external speaker 500 can activate / deactivate the application of sound field effects by equalizer settings according to a command regarding the application of sound field effects.

[0156] In operation S1007, the external speaker 500 can transmit to the display device 100 responses to commands associated with the audio output received from the display device 100. For example, the external speaker 500 can transmit to the display device 100 responses to settings that comply with commands associated with the audio output, responses to predetermined information requested to be transmitted, etc.

[0157] The display device 100 can process audio signals in operation S1008. In the following, the audio signal before processing by the display device 100 via a predetermined audio codec (e.g., Dolby Atmos), predetermined equalizer settings, etc., may be named the first audio signal, and the audio signal after processing may be named the second audio signal. For example, the display device 100 can process the first audio signal using a predetermined audio codec (e.g., Dolby Atmos), predetermined equalizer settings, etc., to generate the second audio signal.

[0158] For example, the display device 100 can process an audio signal using a predetermined audio codec (e.g., Dolby Atmos) to apply a specific sound effect. For example, the display device 100 can process an audio signal to apply a predetermined sound field effect according to a predetermined equalizer setting.

[0159] On the other hand, the display device 100 can process audio signals so that both a specific sound effect using a predetermined audio codec (e.g., Dolby Atmos) and a predetermined sound field effect corresponding to a predetermined equalizer setting are applied.

[0160] The display device 100 can transmit an audio signal to the external speaker 500 in operation S1009. The display device 100 can transmit the audio signal to the external speaker 500 as PCM (Pulse Code Modulation) data.

[0161] The display device 100 can transmit audio signals to external speakers depending on the audio mode.

[0162] For example, when the display device 100 is set to the first audio mode or the second audio mode, it can transmit a second audio signal to the external speaker 500 to which a predetermined sound field effect has been applied. When the audio mode is set to the first audio mode or the second audio mode, the application of the sound field effect by the equalizer setting of the external speaker 500 may be deactivated.

[0163] For example, when the display device 100 is set to the third audio mode, it can transmit a first audio signal to the external speaker 500 to which a predetermined sound field effect is not applied. When the audio mode is set to the third audio mode, the application of the sound field effect by the equalizer setting of the external speaker 500 may be activated.

[0164] The display device 100 can transmit an audio signal to the external speaker 500 depending on whether the external speaker 500 is activated or deactivated with a predetermined audio codec (e.g., Dolby Atmos). For example, when the external speaker 500 is activated with the predetermined audio codec (e.g., Dolby Atmos), the display device 100 can transmit a first audio signal to the external speaker 500 that does not utilize the predetermined audio codec (e.g., Dolby Atmos). For example, when the external speaker 500 is deactivated with the predetermined audio codec (e.g., Dolby Atmos), the display device 100 can transmit a second audio signal to the external speaker 500 that utilizes the predetermined audio codec (e.g., Dolby Atmos) and has specific sound effects applied to it.

[0165] The display device 100 can output audio in operation S1010. For example, the display device 100 can output audio via the speaker based on a delay value relative to the audio output delay of the external speaker 500.

[0166] The external speaker 500 can output audio based on the audio signal received from the display device 100 in operation S1011. The audio signal after the external speaker 500 has processed the audio signal received from the display device 100 using a predetermined audio codec (e.g., Dolby Atmos), predetermined equalizer settings, etc., may be named the third audio signal. For example, the external speaker 500 can generate a third audio signal by processing the audio signal received from the display device 100 using a predetermined audio codec (e.g., Dolby Atmos), predetermined equalizer settings, etc. Here, the external speaker 500 can output audio corresponding to the third audio signal.

[0167] The external speaker 500 can process the audio signal received from the display device 100 depending on whether the application of the sound field effect by the equalizer setting is activated or deactivated. For example, when the application of a predetermined sound field effect is activated, the external speaker 500 can process the audio signal received from the display device 100 with an equalizer setting corresponding to the predetermined sound field effect, and then output the audio corresponding to the processed audio signal. For example, when the application of the sound field effect by the equalizer setting is deactivated, the external speaker 500 can output the audio corresponding to the audio signal received from the display device 100 without any processing of the sound field effect by the equalizer setting.

[0168] The external speaker 500 can process the audio signal received from the display device 100 depending on whether a predetermined audio codec (e.g., Dolby Atmos) is activated or deactivated. For example, when the predetermined audio codec (e.g., Dolby Atmos) is activated, the external speaker 500 can process the audio signal received from the display device 100 so that specific sound effects are applied using the predetermined audio codec (e.g., Dolby Atmos), and then output the audio corresponding to the processed audio signal. For example, when the predetermined audio codec (e.g., Dolby Atmos) is deactivated, the external speaker 500 can output the audio corresponding to the audio signal received from the display device 100 without any processing for specific sound effects using the predetermined audio codec (e.g., Dolby Atmos).

[0169] Referring to the frequency response graph for audio output in Figure 11, graph 1110, which shows no processing for sound field effects by equalizer settings, differs significantly from graphs 1121 to 1126, which show various sound field effects applied. Because the frequency characteristics differ for each sound field effect, different sounds can be transmitted to the user listening to the audio depending on the sound field effect.

[0170] When an audio signal processed for a predetermined sound field effect in the display device 100 is transmitted to the external speaker 500, and the external speaker 500 also processes the audio signal for the predetermined sound field effect, the processing for the predetermined sound field effect is duplicated, resulting in audio output from the external speaker 500 with a sound field effect completely different from the predetermined sound field effect applied. In this case, the audio output from the display device 100 and the audio output from the external speaker 500 may not be provided to the user as a single, unified audio.

[0171] Therefore, when the external speaker 500 receives a second audio signal from the display device 100 to which a predetermined sound field effect has been applied, the external speaker 500 must output the audio corresponding to the audio signal received from the display device 100 without any processing for the sound field effect. This requirement also applies to the application of specific sound effects using a predetermined audio codec (e.g., Dolby Atmos).

[0172] Referring again to Figure 10, the external speaker 500 can transmit battery-related information to the display device 100 in operation S1012. For example, the external speaker 500 can transmit the percentage corresponding to the remaining battery power, the usage time, etc., to the display device 100.

[0173] In operation S1013, the display device 100 can output information regarding the battery of the external speaker 500 via the display 180. For example, the display device 100 can output an indicator of the remaining battery power of the external speaker 500 via the display 180.

[0174] In operation S1014, the display device 100 can output a notification regarding low battery of the external speaker 500. For example, the display device 100 can output a notification via the display 180 indicating an external speaker 500 whose remaining battery power is below a reference value. Here, the display device 100 can output a screen that includes the model name, location, and a message regarding battery charging for the external speaker 500 whose remaining battery power is below a reference value.

[0175] On the other hand, the display device 100 can also output a screen that includes a user interface for setting a low-power mode to reduce power consumption of the external speaker 500 when the remaining battery power is below a standard value.

[0176] The display device 100 can transmit an audio signal corresponding to low battery to an external speaker 500 when the remaining battery power is below a reference value. The external speaker 500, upon receiving the audio signal corresponding to low battery, can output an audio message indicating low battery based on the audio signal received from the display device 100.

[0177] The display device 100 can receive inputs to control the external speaker 500 in operation S1015. For example, the display device 100 can receive a user input from the remote control device 200 to turn the power of the external speaker 500 on / off. For example, the display device 100 can receive a user input from the remote control device 200 to adjust the volume of the external speaker 500. For example, the display device 100 can receive an input to set a low-power mode via a user interface for setting a low-power mode to reduce the power consumption of the external speaker 500.

[0178] In operation S1016, the display device 100 can send commands to the external speaker 500 to control the external speaker 500. For example, in response to user input received from the remote control device 200, the display device 100 can send commands to the external speaker 500 to turn the power on / off, adjust the volume, etc. For example, based on input to set the external speaker 500 to low power mode, the display device 100 can send commands to turn the power off, decrease the volume, etc.

[0179] The external speaker 500 can operate in operation S1017, based on control commands received from the display device 100.

[0180] Figure 12 is a flowchart referenced in the description of the application of sound field effects according to the audio mode and the operation of the related system according to one embodiment of the present disclosure. Detailed explanations of content that overlaps with what has been described above will be omitted.

[0181] As shown in Figure 12, the display device 100 and the external speaker 500 can connect to each other via a Bluetooth communication profile in S1201 operation. For example, the display device 100 and the external speaker 500 can connect to each other via A2DP and AVRCP.

[0182] The display device 100 can transmit device information to the external speaker 500 in operation S1202.

[0183] The external speaker 500 can transmit device information to the display device 100 in operation S1203.

[0184] In operation S1204, the display device 100 can determine the audio mode to be either the first audio mode or the second audio mode based on the settings for surround sound effects and / or the device information of the external speaker 500.

[0185] In operation S1205, the display device 100 can send a command to the external speaker 500 to deactivate the application of sound field effects by equalizer settings (hereinafter referred to as a sound field effect deactivation command) in response to the audio mode being set to the first audio mode or the second audio mode.

[0186] The external speaker 500 can, in operation S1206, cancel the application of the sound field effect based on the equalizer settings, based on the sound field effect cancellation command received from the display device 100. In other words, the external speaker 500 can be set to output the audio corresponding to the audio signal received from the display device 100 as is.

[0187] The external speaker 500 can, in operation S1207, transmit a response to the sound field effect release command to the display device 100. For example, the external speaker 500 can transmit a data value to the display device 100 indicating that the application of the sound field effect by the equalizer setting is released in accordance with the sound field effect release command.

[0188] The display device 100 can process audio signals according to the audio mode in operation S1208. For example, the display device 100 can process audio signals such that a predetermined sound field effect is applied according to a predetermined equalizer setting value that has already been set when used in the display device 100.

[0189] According to one embodiment, the display device 100 can process an audio signal so that a sound field effect is applied according to an equalizer setting value corresponding to the genre of content. For example, the display device 100 can determine the genre of content provided to the display device 100 by checking the content metadata or by analyzing the content based on an algorithm using machine learning. Here, the display device 100 can determine an equalizer setting value corresponding to the genre of content and process the audio signal according to the determined equalizer setting value.

[0190] The display device 100 can transmit a second audio signal to an external speaker 500 with a predetermined sound field effect applied in operation S1209.

[0191] The display device 100 can output audio corresponding to a second audio signal to which a predetermined sound field effect has been applied, via a speaker, in S1210 operation.

[0192] The external speaker 500 can output audio based on a second audio signal to which a predetermined sound field effect is applied, received from the display device 100, in operation S1211. Here, the external speaker 500 can output audio corresponding to the second audio signal received from the display device 100 without processing the sound field effect by equalizer settings.

[0193] This prevents the overlapping application of predetermined sound field effects to the audio signal, allowing both the display device 100 and the external speaker 500 to output audio with the predetermined sound field effects properly applied. Therefore, a single, unified audio with the predetermined sound field effects applied can be provided to the user.

[0194] Figure 13 is a flowchart referenced in other embodiments of this disclosure relating to the application of sound field effects by audio modes and the operation of the associated systems. Detailed explanations of content that overlaps with the preceding text are omitted.

[0195] As shown in Figure 13, the display device 100 and the external speaker 500 can connect to each other via a Bluetooth communication profile in S1301 operation. For example, the display device 100 and the external speaker 500 can connect to each other via A2DP and AVRCP.

[0196] The display device 100 can transmit device information to the external speaker 500 in operation S1302.

[0197] The external speaker 500 can transmit device information to the display device 100 in operation S1303.

[0198] In operation S1304, the display device 100 can determine the audio mode to the third audio mode based on the settings for surround sound effects and / or the device information of the external speaker 500.

[0199] In operation S1305, the display device 100 can send a command to the external speaker 500 requesting the transmission of information regarding a predetermined sound field effect that has already been set, in response to the audio mode being set to the third audio mode.

[0200] The external speaker 500 can maintain the settings for applying already set sound field effects in operation S1306. For example, the external speaker 500 can set equalizer settings corresponding to already set sound field effects so that when the application of sound field effects is activated, the already set sound field effects are applied to the audio signal when used with the external speaker 500. For example, the external speaker 500 can set equalizer settings so that when the application of sound field effects is deactivated, the audio corresponding to the audio signal received from the display device 100 is output as is.

[0201] The external speaker 500 can transmit information about already set sound field effects to the display device 100 in operation S1307. For example, the external speaker 500 can transmit information about activating / deactivating the application of sound field effects, information about already set sound field effects, etc., to the display device 100.

[0202] The display device 100 can adjust settings related to audio output based on information received from the external speaker 500 regarding predetermined sound field effects already set on the external speaker 500. For example, if the application of sound field effects is deactivated on the external speaker 500, the display device 100 can deactivate the application of sound field effects on the display device 100. For example, if the application of sound field effects is activated on the external speaker 500, the display device 100 can set equalizer settings corresponding to predetermined sound field effects already set on the external speaker 500 so that these predetermined sound field effects are applied to the audio signal.

[0203] The display device 100 can process audio signals according to the audio mode in operation S1308. For example, the display device 100 can process audio signals so that a predetermined sound field effect is applied according to an equalizer setting value corresponding to a predetermined sound field effect already set on the external speaker 500.

[0204] The display device 100 can transmit a first audio signal to an external speaker 500 in operation S1309, to which no sound field effect due to equalizer settings has been applied.

[0205] In operation S1310, the display device 100 can output audio corresponding to a second audio signal to an external speaker 500, to which a predetermined sound field effect already set is applied, via the speaker.

[0206] The external speaker 500 can process the first audio signal received from the display device 100 in operation S1311 so that a predetermined sound field effect already set for the external speaker 500 is applied. The external speaker 500 can process the audio signal received from the display device 100 using equalizer settings corresponding to a predetermined sound field effect already set for the external speaker 500.

[0207] The external speaker 500 can output audio corresponding to a second audio signal to which a predetermined sound field effect has been applied, in S1312 operation.

[0208] This prevents the overlapping application of predetermined sound field effects to the audio signal, allowing both the display device 100 and the external speaker 500 to output audio with the predetermined sound field effects properly applied. Therefore, a single, unified audio with the predetermined sound field effects applied can be provided to the user.

[0209] According to one embodiment, when the audio mode is set to the third mode, the display device 100 can also deactivate the application of sound field effects by equalizer settings of the external speaker 500. In this case, the display device 100 can transmit a second audio signal to the external speaker 500 to which a predetermined sound field effect has been applied. Furthermore, the external speaker 500 can output audio corresponding to the audio signal received from the display device 100 without processing the sound field effect by equalizer settings.

[0210] In this case as well, the overlapping application of predetermined sound field effects to the audio signal is prevented, so both the display device 100 and the external speaker 500 can output audio to which the predetermined sound field effect is properly applied. Therefore, a single, unified audio to which the predetermined sound field effect is applied can be provided to the user.

[0211] On the other hand, if the display device 100 does not receive information regarding sound field effects already set on the external speaker 500, it can also deactivate the application of sound field effects via the equalizer settings of the external speaker 500. In this case, the display device 100 can transmit a second audio signal to the external speaker 500 to which the sound field effects already set on the display device 100 are applied.

[0212] Figures 14 to 16 are flowcharts illustrating the operation method of a display device according to one embodiment of the present disclosure. Detailed explanations of content that overlaps with that described in Figures 10 to 13 are omitted.

[0213] As shown in Figure 14, the display device 100 can establish a Bluetooth communication connection with the external speaker 500 in operation S1401. For example, the display device 100 can connect to the external speaker 500 via A2DP and AVRCP.

[0214] The display device 100 can transmit device information to the external speaker 500 in operation S1402.

[0215] In operation S1403, the display device 100 can determine whether or not device information for the external speaker 500 has been received from the external speaker 500.

[0216] In operation S1404, the display device 100 can check whether the number of attempts to receive the device information from the external speaker 500 has been made is less than or equal to a predetermined number (e.g., 3 times) if at least a portion of the device information from the external speaker 500 has not been received.

[0217] The display device 100 can attempt to receive device information from the external speaker 500 again, based on the fact that the number of times it has attempted to receive device information from the external speaker 500 is less than or equal to a predetermined number. For example, the display device 100 can transmit its own device information to the external speaker 500 again. For example, the display device 100 can send a command to the external speaker 500 requesting the transmission of device information from the external speaker 500.

[0218] In operation S1405, the display device 100 can set the audio mode to the basic mode based on the number of times it has attempted to receive device information from the external speaker 500 exceeding a predetermined number. Here, the basic mode may be a mode in which the display device 100 processes the audio signal according to the settings already set in the display device 100, regardless of the external speaker 500, and transmits the audio signal to the external speaker 500.

[0219] The display device 100 can set a delay value for the audio output delay of the external speaker 500 in operation S1406.

[0220] For example, the display device 100 may transmit a pre-configured test audio signal to the external speaker 500 based on its failure to receive device information for the external speaker 500. Here, the display device 100 may send a command to the remote control device 200 to receive audio via the microphone 290.

[0221] The external speaker 500 can output audio corresponding to the test audio signal received from the display device 100. The remote control device 200 can transmit data for the audio received via the microphone 290 to the display device 100. The data for the audio transmitted from the remote control device 200 may include data for the waveform of the audio received via the microphone 290.

[0222] The display device 100 can set a delay value for the audio output delay of the external speaker 500 based on the audio data received from the remote control device 200. For example, the display device 100 can set a delay value for the audio output delay of the external speaker 500 by comparing the audio waveform included in the audio data with the waveform of a test audio signal.

[0223] The display device 100 can process audio signals in operation S1407. The display device 100 can output audio corresponding to the processed audio signal. For example, the display device 100 can process audio signals using a predetermined audio codec (e.g., Dolby Atmos) so that a specific sound effect is applied. For example, the display device 100 can process audio signals so that a predetermined sound field effect is applied according to a predetermined equalizer setting.

[0224] In operation S1408, the display device 100 can transmit an audio signal to the external speaker 500 according to the audio output type. For example, if the display device 100 is set not to provide surround sound effects, it can transmit a second audio signal to the external speaker 500 to which a predetermined sound field effect is applied. For example, if the display device 100 is set to provide surround sound effects, it can transmit a first audio signal to the external speaker 500 to which the predetermined sound field effect is not applied.

[0225] On the other hand, the display device 100 can output audio via a speaker.

[0226] As shown in Figure 15, when the display device 100 receives device information for the external speaker 500 in operation S1501, it can determine whether or not it is an additional connection of the external speaker 500. For example, if the first external speaker 500-1 is already connected to the display device 100, it can determine whether or not the second external speaker 500-2 is to be connected. In the following, the external speaker 500 already connected to the display device 100 will be referred to as the first external speaker 500-1, and the external speaker 500 to be additionally connected will be referred to as the second external speaker 500-2.

[0227] The display device 100 can check whether it is set to provide surround sound effects in operation S1502, unless an additional external speaker 500 is connected.

[0228] If the display device 100 is set not to provide surround sound effects in operation S1503, the audio mode can be set to the first audio mode.

[0229] If the display device 100 is set to provide surround sound effects in operation S1504, it can determine whether the external speaker 500 is a device of a type that has already been set (e.g., a soundbar) based on the device information of the external speaker 500.

[0230] In operation S1505, the display device 100 can set the audio mode to the second audio mode if the external speaker 500 is not a device of a type that has already been set (e.g., a soundbar).

[0231] In operation S1506, the display device 100 can send a sound field effect cancellation command to the external speaker 500 in response to the audio mode being set to the first audio mode or the second audio mode, thereby canceling the application of the sound field effect by the equalizer setting of the external speaker 500.

[0232] The display device 100 can process audio signals according to the first audio mode or the second audio mode in operation S1507. For example, the display device 100 can process audio signals such that a predetermined sound field effect is applied according to a predetermined equalizer setting value that has already been set when used in the display device 100.

[0233] In operation S1508, the display device 100 can transmit an audio signal to the external speaker 500 to which a predetermined sound field effect, which has been set in the display device 100, has been applied.

[0234] The display device 100 can output audio corresponding to an audio signal via a speaker in operation S1509. For example, the display device 100 can output audio corresponding to a second audio signal to which a predetermined sound field effect has been applied.

[0235] On the other hand, in operation S1510, the display device 100 can set the audio mode to the third audio mode if the external speaker 500 is a device of a type that has already been configured (e.g., a soundbar).

[0236] In operation S1511, the display device 100 can obtain information from the external speaker 500 regarding a predetermined sound field effect already set on the external speaker 500. Based on the information received from the external speaker 500 regarding a predetermined sound field effect already set on the external speaker 500, the display device 100 can adjust the settings related to the audio output.

[0237] The display device 100 can process audio signals according to the third audio mode in operation S1512. For example, the display device 100 can process audio signals so that a predetermined sound field effect is applied according to an equalizer setting value corresponding to a predetermined sound field effect already set on the external speaker 500.

[0238] The display device 100 can, in operation S1513, transmit a first audio signal to the external speaker 500 to which no sound field effect due to equalizer settings has been applied.

[0239] As shown in Figure 16, the display device 100 can determine in operation S1601 whether it is set to provide surround sound effects when an additional external speaker 500 is connected.

[0240] If the display device 100 is set not to provide surround sound effects in operation S1602, the audio mode can be set to the first audio mode. For example, if a second external speaker 500-2 is connected while the audio mode is set to the first audio mode, the audio mode will remain in the first audio mode.

[0241] If the display device 100 is set to provide surround sound effects in operation S1603, it can determine whether the first external speaker 500-1 is a device of a type that has already been set (e.g., a soundbar).

[0242] In operation S1604, the display device 100 can determine whether the second external speaker 500-2 is a device of a type that has already been set (e.g., a soundbar) if the first external speaker 500-1 is not a device of a type that has already been set (e.g., a soundbar).

[0243] In operation S1605, the display device 100 can set the audio mode to the second audio mode if neither the first external speaker 500-1 nor the second external speaker 500-2 are devices of a type that has already been configured (e.g., a soundbar). For example, if the audio mode is set to the second audio mode and the second external speaker 500-2 is not a device of a type that has already been configured (e.g., a soundbar), the audio mode will remain in the second audio mode.

[0244] In operation S1606, the display device 100 can send a sound field effect cancellation command to the multiple external speakers 500-1 and 500-2 in response to the audio mode being set to the first audio mode or the second audio mode, thereby canceling the application of the sound field effect by the equalizer settings of the multiple external speakers 500-1 and 500-2.

[0245] The display device 100 can process audio signals according to the first audio mode or the second audio mode in operation S1607.

[0246] In operation S1608, the display device 100 can transmit a second audio signal to a plurality of external speakers 500-1, 500-2 to which a predetermined sound field effect, which has been set when used in the display device 100, is applied.

[0247] The display device 100 can output audio corresponding to an audio signal via a speaker in operation S1609. For example, the display device 100 can output audio corresponding to a second audio signal to which a predetermined sound field effect has been applied.

[0248] On the other hand, in operation S1610, the display device 100 can set the audio mode to the third audio mode if the first external speaker 500-1 is a device of a type that has already been set (e.g., a soundbar) and / or the second external speaker 500-2 is a device of a type that has already been set (e.g., a soundbar).

[0249] For example, if the first external speaker 500-1 is already a configured type of device (e.g., a soundbar), and a second external speaker 500-2, which is also an already configured type of device (e.g., a soundbar), is added, the audio mode can be set to the third audio mode. In this setting, the main audio is output from the first external speaker 500-1 and the sub-audio is output from the second external speaker 500-2.

[0250] For example, if the first external speaker 500-1 is already a configured type of device (e.g., a soundbar), and a second external speaker 500-2, which is also an already configured type of device (e.g., a soundbar), is connected, the audio mode can be set to the third audio mode. Here, the main audio can be output from both the multiple external speakers 500-1 and 500-2, and the sub-audio can be output from the display device 100.

[0251] For example, if the first external speaker 500-1 is not a device of a type that has already been configured (e.g., a soundbar), and a second external speaker 500-2, which is a device of a type that has already been configured (e.g., a soundbar), is added, the audio mode can be set to the third audio mode. In this case, the main audio can be set to be output from the second external speaker 500-2.

[0252] According to one embodiment, when the first external speaker 500-1 is a device of a type that has already been set (e.g., a soundbar), and a second external speaker 500-2, which is also a device of a type that has already been set (e.g., a soundbar), is connected, the display device 100 can output a screen via the display 180 that includes a message asking whether or not to change the setting to not provide surround sound effects. That is, the display device 100 can output a screen via the display 180 that includes a message asking whether or not to set the audio mode to the first audio mode.

[0253] Here, the display device 100 can set the audio mode to a first audio mode based on the reception of user input that changes the setting to not provide surround sound effects. On the other hand, the display device 100 can set the audio mode to a third audio mode based on the reception of user input that maintains the setting to provide surround sound effects.

[0254] According to one embodiment, if the first external speaker 500-1 is a device of a type that has already been configured (e.g., a soundbar), and a second external speaker 500-2, which is also a device of a type that has already been configured (e.g., a soundbar), is connected, the display device 100 may also output a screen via the display 180 that includes a message asking whether or not to set the audio mode to the second audio mode. Here, the display device 100 can set the audio mode to the second audio mode based on the reception of user input to set the audio mode to the second audio mode.

[0255] In the following, the external speaker 500 that outputs the main audio may be named the front speaker, and the external speaker 500 that outputs the sub-audio may be named the surround speaker.

[0256] In operation S1511, the display device 100 can obtain information from the front speaker 500 regarding a predetermined sound field effect already set for the front speaker 500. Based on the information received from the front speaker 500 regarding the predetermined sound field effect already set for the front speaker 500, the display device 100 can adjust the settings related to the audio output.

[0257] On the other hand, if all of the multiple external speakers 500-1 and 500-2 are front speakers, the display device 100 can obtain information about a predetermined sound field effect that has already been set from one of the multiple external speakers 500-1 and 500-2. For example, the display device 100 can obtain information about a predetermined sound field effect that has already been set from the first external speaker 500-1 among the multiple external speakers 500-1 and 500-2. Here, the display device 100 can transmit the information about the predetermined sound field effect received from the first external speaker 500-1 to the second external speaker 500-2. The second external speaker 500-2 can adjust the settings related to the audio output based on the information about the predetermined sound field effect that has already been set and received from the display device 100.

[0258] The display device 100 can process audio signals according to the third audio mode in operation S1612. For example, the display device 100 can process audio signals so that a predetermined sound field effect is applied according to an equalizer setting value corresponding to a predetermined sound field effect already set on the front speaker 500.

[0259] The display device 100 can, in operation S1613, transmit a first audio signal to the front speaker 500 to which no sound field effect due to equalizer settings has been applied.

[0260] In operation S1613, the display device 100 can transmit a second audio signal to the surround speaker 500 to which a predetermined sound field effect has been applied according to an equalizer setting value corresponding to a predetermined sound field effect already set on the front speaker 500.

[0261] According to one embodiment, when a plurality of different external speakers 500-1 and 500-2 are connected via communication, the display device 100 can set a delay value for the audio output delay for each of the plurality of external speakers 500-1 and 500-2. The display device 100 can output audio based on the delay value for the audio output delay set for each of the plurality of external speakers 500-1 and 500-2. For example, the display device 100 can output audio based on the larger of the delay values ​​for each of the plurality of external speakers 500-1 and 500-2. For example, the display device 100 can also output audio based on the average of the delay values ​​for each of the plurality of external speakers 500-1 and 500-2.

[0262] On the other hand, the display device 100 can also transmit audio signals to each of the multiple external speakers 500-1 and 500-2 based on the delay value for the audio output delay set for each of the multiple external speakers 500-1 and 500-2.

[0263] The display device 100 can determine the delay value for the audio output delay for each of the multiple external speakers 500-1 and 500-2 using various methods.

[0264] For example, the display device 100 can transmit a first test audio signal to the first external speaker 500-1 and a second test audio signal to the second external speaker 500-2. The multiple external speakers 500-1 and 500-2 can each output audio corresponding to the test audio signals received from the display device 100. The remote control device 200 can transmit data for the audio received via the microphone 290 to the display device 100. Based on the audio data received from the remote control device 200, the display device 100 can set delay values ​​for the audio output delay for each of the multiple external speakers 500-1 and 500-2.

[0265] For example, the display device 100 can obtain information about the buffer size from multiple external speakers 500-1 and 500-2. Here, the display device 100 can set a delay value for the audio output delay for each of the multiple external speakers 500-1 and 500-2, corresponding to the buffer size received from the multiple external speakers 500-1 and 500-2. The larger the buffer size, the larger the delay value for the audio output delay.

[0266] According to one embodiment, the display device 100 can reset the audio mode if the communication connection of any one of the multiple external speakers 500-1, 500-2 is disconnected. Here, the display device 100 can determine the audio mode based on the settings for surround sound effects and / or the information of one of the multiple external speakers 500-1, 500-2 that is connected via communication.

[0267] According to one embodiment, the display device 100 can determine whether to return to the previous mode, which was set with only the first external speaker 500-1 connected, if the communication connection of any one of the multiple external speakers 500-1, 500-2 is disconnected. For example, if the communication connection of any one of the multiple external speakers 500-1, 500-2 is disconnected, the display device 100 can output a screen via the display 180 containing a message asking whether to return to the previous mode.

[0268] The display device 100 can set the audio mode to the previous mode based on the reception of user input that returns to the previous mode. On the other hand, the display device 100 can determine the audio mode based on the settings for surround sound effects and / or the device information of the communicated external speaker 500 based on the reception of user input that does not return to the previous mode.

[0269] As described above, according to at least one embodiment of the present disclosure, an audio signal optimized for an external speaker can be provided by setting an audio mode corresponding to the external speaker and processing the audio signal.

[0270] Furthermore, according to at least one embodiment of this disclosure, an audio mode corresponding to an external speaker can be recommended.

[0271] Furthermore, according to at least one embodiment of this disclosure, settings for the audio output of external speakers can be controlled according to the audio mode to provide a unified audio.

[0272] Furthermore, according to at least one embodiment of this disclosure, the audio signal can be processed by settings relating to the audio output of an external speaker to provide a unified audio signal.

[0273] Furthermore, according to at least one embodiment of this disclosure, the status of an external speaker can be provided to the user, and control can be performed in accordance with the status of the external speaker.

[0274] As shown in Figures 1 to 16, a display device 100 according to one aspect of the present disclosure includes a display 180; a speaker 185; a wireless communication interface 173 for communicating with at least one external speaker 500; and a controller 170, the controller 170 can send an audio output command to the external speaker 500 based on the speaker 185 and the setting of an audio mode for outputting audio through the external speaker; send a first audio signal to the external speaker 500 corresponding to the command sent to the external speaker 500 being a first command; and send a second audio signal to the external speaker 500 generated by processing the first audio signal corresponding to the command sent to the external speaker 500 being a second command.

[0276] Furthermore, according to one aspect of this disclosure, the controller 170 can receive device information from the external speaker 500, including the type of the external speaker 500, and set the audio mode to a first audio mode if it has already been set to output the same audio via speaker 185 and the external speaker 500; set the audio mode to a second audio mode if it has already been set to output different audio via speaker 185 and the external speaker 500 and the type of the external speaker 500 is not a predetermined type; and set the audio mode to a third audio mode if it has already been set to output different audio via speaker 185 and the external speaker 500 and the type of the external speaker 500 is the predetermined type.

[0277] Furthermore, according to one aspect of this disclosure, the controller 170 can send the second command to the external speaker 500 based on the setting of either the first audio mode or the second audio mode, and send the first command to the external speaker 500 based on the setting of the third audio mode.

[0278] Furthermore, according to one aspect of this disclosure, the controller 170 further includes a user input interface 150 for receiving user input, the controller 170 outputting a screen via the display 180 for setting the type of audio output from at least one of the speaker 185 and the external speaker 500, setting the audio mode to a second audio mode based on a first user input that sets the main audio to be output via the speaker 185 and the sub-audio to be output via the external speaker 500, and setting the audio mode to a third audio mode based on a second user input that sets the sub-audio to be output via the speaker 185 and the main audio to be output via the external speaker 500.

[0279] Furthermore, according to one aspect of this disclosure, the controller 170 can output the already set audio via the speaker 185 in response to the setting of the type of audio output from the speaker 185, and can transmit an audio signal corresponding to the already set audio via the external speaker 500 in response to the setting of the type of audio output from the external speaker 500.

[0280] Furthermore, according to one aspect of this disclosure, the controller 170 may display a first object on the screen recommending the output of the main audio to the external speaker 500 if the type of the external speaker 500 is the predetermined type, and a second object on the screen recommending the output of the sub-audio to the external speaker 500 if the type of the external speaker 500 is not the predetermined type.

[0281] Furthermore, according to one aspect of this disclosure, if the device information is not received from the external speaker 500, the controller 170 can set the audio mode to the fourth audio mode, and if it has already been set to output the same audio via the speaker 185 and the external speaker 500 in the fourth audio mode, it can transmit the second audio signal to the external speaker 500, and if it has already been set to output different audio via the speaker 185 and the external speaker 500 in the fourth audio mode, it can transmit the first audio signal to the external speaker 500.

[0282] Furthermore, according to one aspect of this disclosure, the controller 170 further includes a user input interface 150 for receiving data from a remote control device 200, wherein if the device information is not received from the external speaker 500, the controller 170 can transmit a third audio signal to the external speaker 500, receive data for audio received via a microphone 290 included in the remote control device 200 from the remote control device 200, compare the data for audio with the third audio signal to determine a set value for the delay of the audio output of the external speaker 500.

[0283] Furthermore, according to one aspect of this disclosure, the first command includes a command requesting the transmission of a first setting value associated with the predetermined function that has already been set in the external speaker 500, and the controller 170 can determine a second setting value associated with the predetermined function that has already been set in the display device 100 in response to the first setting value received from the external speaker 500, and process the first audio signal based on the second setting value.
